Both the disposal of wastewater and fracking itself have been identified as causing thousands of earthquakes, mostly small, but some large enough to cause property damage and injure people. Areas close to fault lines are particularly vulnerable. The earthquakes can continue long after the initial activity is over. In BC, Canada’s leading seismologist recommends prohibiting fracking within 5 km of hydroelectric dams.
